Probes and Accessories

The 101A probe set contains one each of the 100A,B,C, and D probes. The three loop probes are sensitive to magnetic fields. They have different diameters, so that the user can select the optimal probe for the frequency of interest. The 100D stub probe is sensitive to electric fields, and offers the best spatial resolution of all.

The 150A EMC probe amplifier is a low-noise, wide-bandwidth amplifier designed for use with the 100 series EMC probes. It features a gain of over 30 dB and a frequency response of 100 kHz to 6 GHz. Its high gain and low noise improve the system sensitivity dramatically.This higher sensitivity allows the user to widen the spectrum analyzer resolution bandwidth, resulting in faster sweeps and measurements.Depending on the model of spectrum analyzer used, sensitivity can be improved by 20 to 30 dB. This improved sensitivity can improve measurement speed by a factor of 10,000 or more. The 150A ships with an universal power supply and a US-style 3-conductor power cord. Other power cords are available for the U.K. and Europe; please call the factory if you'd like one of these alternate power cords.

The 100A is a small, handheld magnetic field probe ideal for locating the sources of EMC emissions. Its integrated electrostatic shield offers good common-mode rejection, and its fine spatial resolution make it easy to track a source of emissions down to the offending component.

The 100B magnetic field probe has the smallest loop of any probe in the series. It offers the best spatial resolution and high-frequency response of the magnetic field probes, but has lower sensitivity than the 100A or 100C.

The 100C magnetic field probe has the largest loop of any probe in the series. It has the best sensitivity of the magnetic field probes. Because the large size of the loop, its high-frequency response and spatial resolution are not as good as the 100A and 100B.

The 100D is an electric field probe, unlike the 100A/B/C. It has the best spatial resolution of all the probes. However, because it is an electric field probe, it does not offer the common mode rejection that the magnetic field probes have.

The 110A probe cable is designed to connect the 100 series probes to the 150A amplifier or other instruments. This double-shielded cable has good RF performance from DC to 6 GHz. Its narrow diameter gives the 110A cable high flexiblity, making it convenient and kink-free when using the probes manually. One end of the cable has a female SMB connector to connect to the probes, and the other end is male SMA. This allows it to connect directly to the 150A amplifier with no adapters.

The 112A cable is designed to connect the 100 series probes to spectrum analyzers or other instruments with Type N connectors. This double-shielded cable has good RF performance from DC to 6 GHz. Its narrow diameter gives the 112A cable high flexiblity, making it convenient and kink-free when using the probes manually. One end of the cable has a female SMB connector to connect to the probes, and the other end is a male Type N connector. This allows it to connect to spectrum analyzers or other equipment with female Type N connectors.

The 114A cable is designed to connect the 150A EMC probe amplifier to spectrum analyzers or other instruments with Type N connectors. This double-shielded cable has good RF performance from DC to 6 GHz. One end of the cable has a male SMA connector to connect to the amplifier, and the other end is a male Type N connector. This allows it to connect to spectrum analyzers or other equipment with female Type N connectors.
